Highlights
- •Organ dose and image quality vary on the exposure arc trajectory in C-arm CBCT.
- •Proposed coefficients may be used to estimate organ dose on the current CBCT unit.
- •Image quality is highest in volumes located close to the system’s isocenter.
- •Selection of task-specific protocol optimizes organ dose at an acceptable level of image quality.
